Abstract: 

Introduction: Reducing pain and enhancement of wound healing have several advantages. Wound healing is a complicated but regular process that includes synchronized and organized phenomena such as paranchyma cells migration, proliferation and synthesis of extracellular matrix proteins. Rate of wound healing is affected by various factors. The aim of our study was to investigate the effects of low power He-Ne laser radiation (630 nm), on metabolic process, cellular proliferation and finally wound repairment.
Methods: In our research, about 50 healthy and mature rats were studied by experimental method. After shaving, small cuts (10 mm) were made at the neck. Then they were divided randomly into control and case groups. The rats of the case group were radiated by He-Ne laser in the wounds about 4 minutes each day. After a week, we did wound autopsy of both groups and all the specimens were studied microscopically.
Results: The findings showed that there were significant increase in the fibroblasts and connective tissue fibers and also vascularisation in the case group compared with the control group.
Discussion: Wound healing in the case group was accelerated and wound diameter was smaller significantly. So, low power He-Ne laser radiation accelerates wound healing process.
